Foundation Engineering...102Most of our textbooks still separate foundation options into two simplistic categories: shallow or deep. That's why so many of us are geared toward thinking about the foundation...

GeneralDesign of Latticed Steel Transmission Structures specifies requirements for the design, fabrication, and testing of members and connections for electrical transmission structures. These...

Loading, Geometry, and AnalysisThis Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...

Design of ConnectionsBolted connections for transmission structures are normally designed as bearing type connections. It is assumed that bolts connecting one member to another carry the load in the connection...

TestingThe purchaser shall specify in the contract documents which structures or components of structures are to be tested. If a proof test of a structure or a component of a structure is specified,...

Detailed Site InvestigationsThis section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...

Microtunneling Design ElementsThe design elements and the process for a microtunneling project are generally the same as for other underground projects. Design elements include the following: General conditions; Special...

Pipe CharacteristicsMicrotunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Construction Support ServicesA preconstruction survey of existing structures within the anticipated construction zone of influence should be conducted before any construction begins. A plan for structures that need...

The New Bedford Marine Commerce TerminalWhen construction of the first American offshore wind farm support terminal encountered greater challenges than expected, jet grouting enabled construction to continue....

Performance Limits for Deepwater PipelinesThis paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...

Failure of a Twenty-Foot High Retaining WallA cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....
